摘　　要：换热设备经过一段时间的使用会产生污垢并影响传热效率。对比分析了自动旋转螺旋线传热技术、塑包螺旋线传热技术、振动螺旋线技术、往复螺旋技术、往复弹簧节技术、振动往复螺旋技术等6种不同传热技术的结构组成、工作原理、防垢能力及效果等。在换热管内插入螺旋线在一定程度上可以起到在线除垢防垢和强化传热的双重作用。结合几种常见的换热管内安置螺旋线内插物,根据具体插入螺旋线方式的不同,结构原理不同,除垢效果和防垢能力亦不相同。通过对比分析,提出了除垢技术的研究方向。Heat transfer equipment has been used for a period of time will have dirt and affect heat transfer efficiency.Comparative analysis of the automatic rotation spiral heat transfer technology, plastic bag spiral heat transfer technology, vibration spiral technology, reciprocating screw technology, the shuttle spring festival technology, vibration reciprocating screw technology, six different heat transfer technology structure, working principle, scale effects, the ability to insert and spiral tubes in a certain extent, you can play online Anti-fouling and strengthening the dual role of heat transfer.Inner tubes combine several common interpolation was placed inside helix, depending on the different structural principle spiral insert specific way of cleaning effect and scale capacity is not the same.By comparison analysis, the research directions cleaning technology.
